| description | In this paper, the velocity and pressure drop distribution in flowing
water through circular, square, rectangular with aspect ratio of 2:1 and
4:1 as well as an equilateral triangle cross-sectional ducts with the same
duct length and hydraulic diameter have been numerically studied
using ANSYS FLUENT tools. The boundary conditions used for the
simulation are: at the entrance a velocity inlet of 0.2 m/s at 25
C constant temperature, at exit a pressure outlet with zero gage pressure
and a non-slip is used for the duct walls condition. A steady state and kepsilon
turbulence flow model is used. The results have shown that
velocity in the ducts gradually increases from zero at the walls to the
maximum at the center. In the circular duct 20.327%, 15.273%, 13.5%
and 6.834% more pressure is lost than in triangular, square, rectangular
aspect ratio of 2:1 and rectangular aspect ratio of 4:1 ducts respectively.
In turn, circular duct requires the highest pumping power while
triangular one needs the lowest. |
